CHANGE YOUR OIL NOW!!!! this engine is not a PD engine it is the VE engine you will do damage running this on PD oil give it an oil flush then change it to standard diesel oil with a new filter. who told you this engine is a PD? this is the older ( more reliable ) VE engine with the mechanical pump the PD has common rail and expensive electronic injectors!! great cars though if serviced well and with the correct fluids will last for ever. is it the AFN or the AHF engine? there more or less the same engines and are bullet proof. get the EGR blanking plate fitted and if you get chance clean out the inlet manifold. youll gain better mpg and it will be more responsive. EDIT: the correct oil for youre car is 5w-30 use a good quality oil in it and it will run for ever..
